If you are creating a reading plan for 2021, be aware there seems to be a bug where if you do the following, Logos will crash and you will not be able to get back in...this happens in L9 beta but may happen in other versions.
Repeatable from the following steps.
(Don't do this if you absolutely need to use Logos today or are not happy potentially losing all your Reading Plans.)
Logos then crashes and will crash whenever trying to reopen the program.
If you do not do steps 2 and 3 but go straight to 4, the plan seems to create ok with no crashes.

Bump - I can confirm this does happen in 9.1 also.
